SUMMARY OF THE INVENTION

The present invention provides novel compounds of formula I wherein W₁, W₂, W₃, W₄, W₅, B, X₁, X₂, X₃, X₄, X₅, E and L are as defined herein; invention compounds are gamma amino butyric acid receptor-subtype B (“GABA_(B)”), positive allosteric modulators (enhancers), which are useful to provide methods of treating or preventing diseases or disorders, including treatment of anxiety, depression, epilepsy, schizophrenia, cognitive disorders, spasticity and skeletal muscle rigidity, spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, cerebral palsy, neuropathic pain and craving associated with cocaine and nicotine, panic disorder, posttraumatic stress disorders, urge urinary incontinence, gastroesophageal reflux disease, transient lower oesophageal sphincter relaxations, functional gastrointestinal disorders and irritable bowel syndrome.

BACKGROUND OF THE INVENTION

The amino acid GABA (γ-aminobutyric acid) is the main inhibitory neurotransmitter in the adult mammalian brain and regulates many physiological and psychological processes. GABA acts through two major classes of receptors: ionotropic GABA_(A) (including GABA_(C)) receptors and metabotropic GABA_(B) receptors (Hill and Bowery, Nature 1981, 290, 149-152; Bormann, J., Trends Pharmacol. Sci. 2000, 21, 16-19). GABA_(B) receptors are present in most regions of the mammalian brain on presynaptic terminals and postsynaptic neurons, and are involved in the fine-tuning of inhibitory synaptic transmission. Due to their strategic position in neuronal networks to modulate the activity of the various neurotransmitter systems, GABA_(B) receptors are a target of choice for pharmacological agents intended to treat central and peripheral nervous systems disorders (Bettler et al., Physiol Rev. 2004, 84, 835-867; Cryan and Kaupmann, Trends Pharmacol Sci. 2005, 26, 36-43).

The GABA_(B) receptor belongs to the Class-III family of G protein-coupled receptors (GPCRs), as are the receptors for glutamate, Ca²⁺, pheromones and putative taste compounds (Pin et al., Pharmaco. Ther. 2003, 98, 325-354). All members of this family share the characteristic of a large extracellular amino-terminal domain that contains a so-called “Venus Flytrap” orthosteric ligand binding site and seven transmembrane (7TM) helical segments plus an intracellular carboxyl-terminal domain that are involved in receptor activation and G-protein coupling (Bockaert and Pin, EMBO J. 1999, 18, 1723; Galvez et al, J. Biol. Chem. 1999, 274, 13362-13369). A distinct feature, however, of the GABA_(B) receptor is that it operates as a heterodimer of at least two homologous subunits termed GABA_(B1) and GABA_(B2) (Kaupman et al, Nature 1997, 386, 239-246; Gordon et al, J. Biol. Chem. 1999, 12, 7607-7610; Margeta-Mitrovic et al, PNAS 2001, 98, 14649-14654; Bettler et al, Physiol Rev. 2004, 84, 835-867). Orthosteric GABA_(B) receptor ligands bind only at the N-terminal Venus flytrap region of the GABA_(B1) subunit, which in turn activates the associated GABA_(B2) subunit of the heterodimer. It is this later subunit that is responsible for coupling and activation of G-protein (Galvez et al, EMBO J. 2001, 20, 2152-2159; Duthey et al, J. Biol. Chem. 2002, 277, 3236-3241; Pin et al, Biochem. Pharmacol. 2004, 68, 1565-1572). The resulting effect is an inhibition of the adenylyl cyclase activity and subsequent cyclic AMP formation and the modulation of activity of inwardly rectifying potassium channels and voltage-sensitive calcium channels.

Several studies using knock-out (KO) mice have demonstrated the role of the heterodimeric GABA_(B1B2) receptor in several CNS disorders. Mice lacking the GABA_(B1) subunit exhibit spontaneous seizures and hyperalgesia (Schuler et al, Neuron 2001, 31, 47-58). These behavioral characteristics are paralleled by a loss of all biochemical and electrophysiological GABA_(B) responses in these KO mice. In these studies, a clear impairment of passive avoidance performance was also observed indicating impaired memory processes. GABA_(B1) deficient mice were also found to be more anxious than their wild-type counterparts (Mombereau et al, Neuropsychopharmacology 2004, 29, 1050-1062). Analogous results were obtained with GABA_(B2) KO mice, which presented all the same behavioural characteristics than the one observed for the GABA_(B1) KO mice (Gassman et al, J. Neurosci. 2004, 24, 6086-6097). Moreover, it has also been shown that a hypoactivity of the GABA system was linked to spasticity, epilepsy, anxiety, stress, sleep disorders, depression, addiction, and pain (Dalvi and Rodgers, Psychopharmacology 1996, 128, 380-397; for a recent review Ong and Kerr, CNS Drug Dev. 2005, 11, 317-334); while on the contrary, a hyperactivity of the GABAergic system was associated with schizophrenia (Blum and Mann, Int. J. Neuropsychopharmacol. 2002, 5, 159-179).

Baclofen is a potent and selective agonist at the GABA_(B) receptor and is presently a frequently and only used clinical drug in the treatment of spasticity and rigidity (Montane et al, Neurology 2004, 63, 1357-1363). Moreover, all effective pharmacological agents used to treat panic disorder increase GABA synaptic transmission and anxiolytics and antidepressants that lack GABA activity are not effective in panic disorders. Baclofen was shown to be significantly effective in reducing the number of panic attacks and symptoms of anxiety as assessed with the Hamilton anxiety scale, Zung Scale, and Katz-R nervousness subscale (Breslow et al, Am. J. Psychiatry 1989, 146, 353-356). Drake and co-workers, hypothesized that baclofen would be an effective treatment in the symptomatic management of veterans with chronic posttraumatic stress disorder (PTSD). Their results demonstrated that the therapy, well tolerated, resulted in significant improvements of the overall symptoms of PTSD and co-morbide depression and anxiety in patients with chronic PTSD due to combat (Drake et al, Ann. Pharmacother. 2003, 37, 1177-1181). More recently, a study looking at the effect of baclofen on the prepulse inhibition (PPI) of the acoustic startle response (ASR), proposed GABA_(B) receptors as putative new targets in the pharmacological therapy of psychotic disorders (Bortalo et al, Psychopharmacology 2004, 171, 322-330). Despite the demonstration of baclofen as being a potential therapeutic tool for the treatment of disorders such as anxiety and spasticity, its use has been limited due to its poor blood-brain-barrier penetration, very short duration of action, muscle relaxing property, hypothermic and sedative side effects, as well as patients' increasing tolerance (Hefferan et al, Neuroscience Letters 2006, 403, 195-200).

A new avenue for developing selective compounds acting at GPCRs is to identify molecules that act through allosteric mechanisms, modulating the receptor by binding to a site different from the highly conserved orthosteric binding site. This concept has assumed a greater importance in the pharmacology of family III receptors in general. For example, allosteric modulators have been described for Ca²⁺-sensing receptors (Nemeth et al, U.S. Pat. No. 6,031,003), for metabotropic glutamate receptors (reviewed in Mutel, Expert Opin. Ther. Patents 12:1-8, 2002; Ritzen, Mathiesen and Thomsen, Basic Clin. Pharmacol. Toxicol 97:202-13, 2005), and most recently for GABA_(B) receptors (Urwyler et al, Mol. Pharmacol. 2001, 60, 963-971; WO 2005/094828; WO 2006/001750; WO 2006/063732; WO 2006/048146; WO 2006/07486; WO 2006/136442; WO 2007/014843; US 2007/027204; WO 2007/073297; WO 2007/073298; WO 2007/073299; WO 2007/073300). These ligands do not activate the receptor by themselves, but, for example in the case of the GABA_(B) receptor, increase the potency of GABA in the presence of this endogenous agonist (Pin et al, Mol. Pharmacol. 2001, 60, 881-884; Urwyler et al, Neuropharmacol. 2005, 48, 343-353). Mutational analyses have demonstrated unequivocally that the binding of known GABA_(B) receptor positive allosteric modulators does not occur at the orthosteric site, but instead at an allosteric site within the seven transmembrane region of the GABA_(B2) subunit at least for CGP7930 (Binet et al, J. Biol. Chem. 2004, 279, 29085-29901).

As a therapeutic principle, positive allosteric modulators are expected to have several advantages over compounds acting as orthosteric agonists, because they are only effective in the presence of the endogenous ligand and therefore act in line with physiological neurotransmission in its temporal and spatial organization. Orthosteric agonists, on the other hand, activate receptors independently of synaptic activity, possibly leading to unwanted side effects.

Cryan and co-workers suggested in a recent study, using GS39783 (N,N′-Dicyclopentyl-2-methylsulfanyl-5-nitro-pyrimidine-4,6-diamine), that a positive modulation of GABA_(B) receptors may serve as a novel therapeutic strategy for the development of anxiolytics with a better side effect profile as compared to baclofen (Cryan et al, J. Pharm. Exp. Therap. 2004, 310, 952-963). They showed that GS39783 is active in models of anxiety such as elevated plus maze (rat), elevated zero maze (mice and rats), and the stress-induced hyperthermia (mice) tests. Moreover, as expected for a positive allosteric modulator that do not have any effect on receptor activity in absence of GABA, but do enhance allosterically the affinity of the GABA_(B) receptor for the endogenous GABA, no side effect on locomotor activity, rotarod, body temperature and traction test was observed for doses ranging from 0.1 to 200 mg/kg, p.o. In comparison baclofen presented those side effects even at efficacious doses in anxiety models. In conclusion, those data suggest that GS39783, and positive allosteric modulators of GABA_(B) receptors in general, are useful and innovative anxiolytics without side-effects associated with baclofen. An interesting example of the use of such compounds in preclinical studies have been done for CGP7930 and GS39783 for the treatment of Gastro-Esophageal Reflux Disease (GERD) and cocain self-administration in rats, where those compounds were found active (Smith et al, Psychopharmacology 2004, 173, 105-111; WO 03/090731).

Recently the 3,3′-diarylpropyl-1-arylethylamines and 3-aryl propyl-1-arylethylamine have been reported as a new class of GABA_(B) receptor modulators as they potentiate baclofen-induced responses in the brain (Kerr et al, Aust. J. Chem. 2006, 59, 445-456) and they modulate both pre- and postsynaptic GABA_(B) receptors in rat brain slices (Ong et al, Eur. J. Pharm. 2005, 507, 35-42).

Patent Publications DE10255416 and WO9730980 describe triazinediones derivatives having herbicidal properties. These triazinediones are also described in the field of fungicide (EP0438717), growth of protozoa (EP0232932, WO00006172), binding to PPAR-α and -γ (FR02866339), P2X7 inhibitors (US25288288, WO04058270) and IL-5 production inhibitors (WO09902505).

None of the specifically disclosed compounds are structurally related to the compounds of the present invention. It has now surprisingly been found that the compounds of general Formula I show potent activity and selectivity on GABA_(B) receptor.

The present invention relates to a method of treating or preventing a condition in a mammal, including a human, the treatment or prevention of which is affected or facilitated by the neuromodulatory effect of GABA_(B) modulators.

Synthesis

Compounds of general formula I may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthesis schemes. In all of the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles of chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Green and P. G. M. Wuts (1991) Protecting Groups in Organic Synthesis, John Wiley et Sons). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection of process as well as the reaction conditions and order of their execution shall be consistent with the preparation of compounds of formula I.

The compound of formula I may be represented as a mixture of enantiomers, which may be resolved into the individual pure R- or S-enantiomers. If for instance, a particular enantiomer of the compound of formula I is desired, it may be prepared by asymmetric synthesis, or by derivation with a chiral auxiliary, where the resulting diastereomeric mixture is separated and the auxiliary group cleaved to provide the pure desired enantiomers. Alternatively, where the molecule contains a basic functional group such as amino, or an acidic functional group such as carboxyl, this resolution may be conveniently performed by fractional crystallization from various solvents, of the salts of the compounds of formula I with optical active acid or by other methods known in the literature, e.g. chiral column chromatography.

Resolution of the final product, an intermediate or a starting material may be performed by any suitable method known in the art as described by E. L. Eliel, S. H. Wilen and L. N. Mander (1984) Stereochemistry of Organic Compounds, Wiley-Interscience.

All the products generated from the following reactions can be isolated and purified employing standard techniques, such as extraction, chromatography, crystallization, distillation, and the like.

General routes to prepare the Examples of the present invention are shown in the Schemes and Examples that follow.

All substituents in the synthetic Schemes unless otherwise indicated, are as previously defined.

The compounds of Formula I may be prepared by general route of synthesis as disclosed in the following methods.

The compounds of Formula III wherein B, L, X₁, X₂, X₃, X₄, X₅ and -E are as described above may be prepared following a cyclisation reaction key step presented in Scheme 1. The amine 1.1 react with the corresponding carboxylic 1.2 acid in a classic peptidic coupling condition (Piskunova, I. P. & al. Tetrahedron 1993, 49(21), 4671-4676) where E can be different electroattractive substituants, i.e —CN to generate 1.3. Then 1.3 can react with the diazonium salt already obtained by mixing the aniline 1.4 with NaNO₂ to generate 1.5 (Bilek, P.; Slouka, J. Heterocycl. Commun. 2004, 10(1), 67-70). The final compound 1.6 is obtained by reaction of the intermediate 1.5 with ethylchloroformiate in a presence of pyridine.

Alternatively the E substituent can be introduced at a late stage in the synthesis, to provide the compounds of Formula III (Scheme 2). Thus the uracyl derivative is brominated to lead to the intermediates 2.1 (Dudfield, P. J. & al. J. Chem. Soc. Perkin Trans. 1, 1999, 20, 2929-2936). The introduction of the L-B group can be achieved through alkylation of 2.2 with Z-L-B (Z=Br, Cl, I, Mesylate, Tosylate, Triflate, OH) in presence of a suitable base such as K₂CO₃, NaH or using a Mitsonobu condition (Z=OH) (Pontillo, J. & al. Bioorg. Med. Chem. Lett. 2005, 15(19), 4363-4366) to afford the intermediate 2.3. Introduction of the suitable substituted aryl/heteroaryl boronic acid is achieved in a presence of copper salt (Lam, P. Y. S. & al. Tetrahedron Lett. 2001, 42, 3415-3418) to afford the compound 2.4. Displacement of the bromoderivative 2.4 by suitable nucleophiles such as amine alcohol in conditions known to the skilled in the art and exemplified in this document lead to compound of formula 2.5 where E=(OR¹², NR¹³R¹⁴), G=(H or a counterion). Additionally reaction of 2.4 with organometallics such as organozinc organoboron, organotin reagent in a presence of palladium catalyst and a co-solvent (M is a metal, zinc or boron or tin or silicon) afford 2.5 whereas E=(alkylaryl, alkyl, heteroaryl, aryl and the like).

Yet another approach to the cpds of Formula III can be represented with the introduction of the L-B group at the final stage of the synthesis (Scheme 3). To achieve such procedure bromouracyl is protected using a suitable protecting group (P.G.) such as benzyl or allyl by reaction of 2.2 with benzyl bromide to afford the intermediate 3.1. The introduction of the suitable substituted aryl/heteroaryl boronic acid is the same as reported in previous scheme to afford 3.2. The displacement of the bromoderivative was done as reported in Scheme 2 to afford 3.3. Deprotection of the amide moiety can be achieved with palladium or ruthenium catalyst in presence of nucleophile such as acetate in a manner well known to those skilled in the art. The introduction of the L-B group proceeds in a similar manner described in Scheme 2 to afford the compound of Formula III (ie 3.5).

A similar procedure as those described in Scheme 2 and 3 can be used starting from commercially available uracyl 4.1 (E=H or CH₃). The introduction of the L-B group can be achieved through alkylation of 4.1 with Z-L-B (Z=Br, Cl, I, Mesylate, Tosylate, Triflate, OH) in presence of a suitable base such as K₂CO₃, NaH or using a Mitsonobu condition (Z=OH) (Pontillo, J. & al. Bioorg. Med. Chem. Lett. 2005, 15(19), 4363-4366) to afford the intermediate 4.2. The introduction of the suitable substituted aryl/heteroaryl boronic acid is the same as reported in a Scheme 2 to afford compound of Formula III (i.e 4.3).

Yet another approach to the compound of Formula III is described in Scheme 5 in particular for those compounds of Formula III for which the introduction of the aryl or heteroaryl through Cham Lam coupling is difficult. In those cases the azalactam ring already was bearing the aryl substituent. 5.4 is built from the open intermediate 5.3 which is cyclised in basic medium. The intermediate 5.3 was obtained by condensation of a diazonium salt of suitably substituted aniline (in this case R⁶=NO₂) with ethyl 2-cyanoacetylcarbamate Further transformation of the E substituent when E=CN in compound of Formula III can be performed (see also Scheme 7 & 8). Thus decyanation was achieved via a two step procedure known in the art such as hydrolysis to the acid and decarboxylation of the acid bearing intermediate (Falco & al. J. Am. Chem. Soc. 1956, 78, 1938-1939). By extention further transformation of the R⁵ group can be also performed such as transformation of the nitro group to an acetamido group. The target compound is then obtained by introduction of the L-B group in a manner similar as that reported in previous to afford the compound 5.7.

Additional possibility of introducing the L-B group at a final stage of the synthesis of compound of Formula III, proceed through clivative alkylation procedure (Scheme 6). Thus 6.1 (described in Collect. Czechoslov. Chem. Commun. 1961, 26, 986-997; Collect. Czechoslov. Chem. Commun. 1975, 40, 2326-2339) is subjected to the Cham Lam coupling in order to introduce the aryl or heteroaylboronic acid in a manner similar to that described in previous schemes to afford 6.2. The clivative alkylation procedure can be performed with a Z-L-B (Z=Br, Cl, I, Mesylate, Tosylate, Triflate,) in presence of sodium iodide (NaI) under microwave irradiation to afford compounds of Formula III (i.e 6.3).

The compounds of Formula III wherein B, L, X₁, X₂, X₃, X₄, X₅ are as described above and E=COOH is an important intermediate may be prepared following one variation presented Scheme 7. The commercially available aniline 7.1 is able to react with sodium nitrite in acidic media to generate a diazo intermediate which is able to react with the commercially available compound 7.2 to form the compound 7.3. In a basic condition, the cyclisation of 7.3 can occur to form the disubstituted azauracil 7.4. This intermediate can react with different halogenalkylaryl (Z=Br, Cl, I, Mesylate, Tosylate, Triflate) in a presence of base to obtain the compound 7.5. After refluxing the compound 7.5 in a presence of HCl 6N the nitrile function is transformed into a carboxylic acid function and in a same time the deacetylation of the acetamido is realised. The compound 7.6 can be obtained after acetylation of the aniline. The carboxylic acid function can be transformed in ester function (Colletti, S. L. & al. Tetrahedron Lett. 2000, 41(41), 7825-7830) and can be reduce in a presence of sodium borohydride to get the alcohol. This alcohol can then react with the phosphorus(III)bromide (Rastelli, G. Bioorg. Med. Chem. Lett. 1997, 7(14), 1897-1902) or with sodium iodide (Baldwin, J. E. Tetrahedron 1991, 47(24), 4089-4100) to afford the bromo or iodo derivative. These halo derivatives could then react with different nucleophile (Nu-H) to obtain the compound 7.12.

The compounds of Formula III wherein B, L, X₁, X₂, X₃, X₄, X₅ are as described above and E=CN is an important intermediate for further reactions. Some transformations of the nitrile organic function are presented in Scheme 8. Thus, derivative 8.1 obtained following the Scheme 1 can be hydrolised into the corresponding carboxylic acid in conditions described in previous schemes. The acid function can itself be the starting for the formation of several heteoaryl groups in manner known to the skilled in the art and are supported in literature in books (Katrizky A. R. and. Rees C. W. (1984) Comprehensive Heterocyclic Chemistry, Pergamon Press), but not limited to. In particular treatment of the acid with hydroxyacetamidine followed by cyclisation of the intermediate acylamidoxine will lead to the suitable substituted oxadiazole. Alternatively, the nitrile function can be easily transformed into precursor of heterocycles, i.e N-((dimethylamino)methylene)acetamide (two steps: transformation to acylamide and reaction with DMF-DMA) or N-hydroxyformimidamide (in direct reaction with suitable hydroxylamine).

The compounds of Formula III wherein B, L, X₁, X₂, X₃, X₄, X₅, E are as described above and R⁶ is NO₂, NR⁸R⁹, OR′ or CN could give compounds of Formula III where R⁶ was transformed into NR⁸R⁹, substituted heteroaryl or substituted heterocycloalkyl are presented in Scheme 9. Thus, derivative 9.1, with R⁶ is —NO₂ can be reduced in primary amine function. The amine function can itself be the starting for the formation of several amide by acylation reaction, secondary or tertiary amine by alkylation reaction and substituted heterocycloalkyl groups in manner known to the skilled in the art and are supported in literature in books (Katrizky A. R. and. Rees C. W. (1984) Comprehensive Heterocyclic Chemistry, Pergamon Press), but not limited to. When derivative 9.1, with R⁶ is NR⁸R⁹ can be reduce or deprotected to give the corresponding primary amine, secondary amine which can react as describe before. With R⁶ is —OR⁷, the deprotection reaction can occur, i.e with BBr₃ to give the alcohol. Then when R⁶ is CN the reactions already describe in the Scheme 8 can be realised to finally conduct to heteroaryl.

Pharmacology

The compounds provided in this invention are positive allosteric modulators of metabotropic GABA receptors; in particular they are positive allosteric modulators of GABA_(B) receptors. The compounds of the present invention do not appear to bind to the GABA recognition site, the orthosteric ligand site, but instead to an allosteric site within the seven transmembrane region of the receptor. In the presence of GABA or an agonist of GABA_(B) receptor, the compounds of this invention increase the GABA_(B) response.

Hence, the present invention relates to a compound or a pharmaceutical composition for the manufacture of a medicament for treating or preventing a condition in a mammal, including a human, the treatment or prevention of which is affected or facilitated by the neuromodulatory effect of GABA_(B) allosteric modulators, in particular positive GABA_(B) allosteric modulators.

The pharmacological activity of positive allosteric modulators, such as the ones described in Formula I, at GABA_(B) receptors is demonstrated in the following paragraphs.

Example A [³⁵S]GTPγS Binding Assay

The [³⁵S]GTPγS binding is a functional membrane-based assay used to study G-protein coupled receptor (GPCR) function. This method consists of using a binding assay to assess the initial step in receptor-mediated G protein activation in membranes prepared from cells expressing recombinant GPCR or using membranes from discrete areas of the rat brain. In brief, the assay measures the activation of G proteins by catalyzing the exchange of guanosine 5′-diphosphate (GDP) by guanosine 5′-triphosphate (GTP) at the α subunit. The GTP-bound G proteins dissociate into two subunits, Gα-GTP and Gβγ, which in turn regulate intracellular enzymes and ion channels. GTP is rapidly hydrolysed by the Gα-subunit (GTPases) and the G protein is deactivated and ready for a new GTP exchange cycle (Harper, Curr. Protoc. Pharmacol. 1998, 2.6, 1-10, John Wiley & Sons, Inc.). [³⁵S]GTPγS, a non-hydrolyzed analogue of GTP, is used for this purpose.

This method is widely used to study receptor activation of G protein in membranes prepared from rat brain tissue, including GABA_(B) receptors (Urwyler et al, The Journal of Pharmacol. and Exp Ther. 2003, 307, 322-330; Olianas et al, Neurochemistry Intern. 2005, 46, 149-158). GABA_(B) receptors are expressed in the rat brain cortex (Odagaki and Yamauchi, Basic Clin. Pharmacol. Toxicol. 2004, 94, 89-98) and are coupled to Gαo/i-protein, a preferential coupling for this method.

[³⁵S]GTPγS binding assay using cortical rat brain membranes preparation was used and adapted from Olianas et al (Neurochemistry Intern. 2005, 46, 149-158) for the detection of the positive allosteric modulator properties of the compounds of this invention on native rat GABA_(B) receptors.

Membrane Preparation.

Cortices were dissected out from brains of 200-300 g Sprague-Dawley rats (Charles River Laboratories, L'Arbresle, France). Tissues were homogenized in 6 volumes (vol/wt) of 10% sucrose at 4° C. using a glass-teflon homogenizer. The homogenate was centrifuged at 1,250 g for 10 min, and the supernatant was centrifuged at 40,000 g for 20 min (4° C.). The pellet was resuspended in 25 ml water using a Polytron disrupter (Kinematica A G, Luzern, Switzerland) and centrifuged for 10 min at 3000 g. (4° C.). The supernatant was centrifuged at 40,000 g for 20 min (4° C.). The supernatant was discarded and the pellet washed twice by resuspension in 10 volumes 5 mM HEPES-KOH, pH 7.4. The homogenate was frozen and thawed twice and centrifuged at 40,000 g for 20 min. The final pellet was resuspended in 5 mM HEPES-KOH, pH 7.4 and stored at −80° C. before its use. Protein concentration was determined by the Bradford method (Bio-Rad protein assay, Reinach, Switzerland) with bovine serum albumin as standard.

[³⁵S]GTPγS Binding Assay.

Measurement of GABA_(B) receptor positive allosteric modulator properties in rat cortical membranes was performed as follows: rat cortical membrane (1.5 μg) were incubated in 96-well microplates for 15 min at 30° C. in assay buffer (50 mM HEPES pH 7.4, 100 mM NaCl, 5 mM MgCl₂, 10 μM GDP, 10 μg/ml saponin, 1 mM CaCl₂) with increasing concentrations of positive allosteric modulator (from 1 nM to 60 μM) and a minimal concentration of GABA or Baclofen, a selective GABA_(B) receptor agonist, that has been determined in previous experiments to correspond to the EC₅₀, a concentration that gives 50% of the maximal response of the agonist, and is in accordance with published data (Olianas et al, Neurochemistry Intern. 2005, 46, 149-158). After addition of 0.1 nM [³⁵S]GTPγS to achieve a total reaction volume of 200 μl, microplates were shaken for 1 min and further incubated at 30° C. for 30 min. The incubation was stopped by rapid vacuum filtration over glass-fiber filter plates (Unifilter 96-well GF/C filter plates, Perkin-Elmer, Schwerzenbach, Switzerland) using a 96-well plate cell harvester (Filtermate, Perkin-Elmer, Downers Grove, USA). The Unifilter plate was washed three times with 300 μl of ice-cold wash buffer (20 mM HEPES pH 7.4, 100 mM NaCl). When filters were dry, 40 μl of liquid scintillation cocktail (Microscint 20) was added to each well. The amount of membrane-bound [³⁵S]GTPγS was measured using a 96-well plate reader (Top-Count, Perkin-Elmer, Downers Grove, USA). Non specific [³⁵S]GTPγS binding is determined in the presence of 10 μM of GTP.

Data Analysis.

The concentration-response curves of representative compounds of the present invention in the presence of EC₅₀ of GABA_(B) receptor agonist were generated using the Prism Graph-Pad program (Graph Pad Software Inc, San Diego, USA). The curves were fitted to a four-parameter logistic equation (Y=Bottom+(Top-Bottom)/(1+10̂((LogEC₅₀−X)*Hill Slope) allowing determination of EC₅₀ values. Each curve was performed using duplicate sample per data point and 10 concentrations. The concentration-response curves of a selective GABA_(B) receptor agonist in the absence or in the presence of representative compounds of the present invention were also generated using Prism Graph-Pad program (Graph Pad Software Inc, San Diego, USA). The curves were fitted to a four-parameter logistic equation (Y=Bottom+(Top-Bottom)/(1+10̂((LogEC₅₀−X)*Hill Slope) allowing determination of EC₅₀ values of the selective GABA_(B) receptor agonist. Each curve was performed using duplicate sample per data point and 10 concentrations.

Data presented in FIGURE A represent the ability of 10 μM of the Compound 4.02 to increase the [GTPγ³⁵S] binding induced by 15 μM of Baclofen, a GABA_(B) receptor agonist. Said example has no statistically significant agonistic activity when tested in the absence of 15 μM Baclofen (1% of maximal response, as a comparison, buffer is 0% of maximal response). Instead, when compounds are added together with a GABA_(B) receptors agonist like Baclofen, the effect measured is significantly potentiated compared to the effect of the agonist alone at the same concentration. Each bar graph is the mean and S.E.M. of duplicate data points and is representative of at least two independent experiments.

Table 8 shows representative compounds of the present invention that were clustered into four classes according to their ability (EC₅₀) to potentiate an EC₅₀ of GABA_(B) receptor agonist such as Baclofen. Class A: EC₅₀<100 nM; Class B: 100 nM<EC₅₀<500 nM; Class C: 500 nM<EC₅₀<1000 nM; Class D: EC₅₀>1000 nM.

Example B Marble Burying Test, Model of Anxiety in Mice

Anxiety models in rodents are used as standard tests to demonstrate anxiolytic-like properties of novel compounds. Mice exhibit a tendency to bury harmless novel objects when encountered in a test cage. Marble burying behavior in mice is reduced by compounds which are efficacious anxiolytics in humans. Thus, marble burying in mice has been used as a model for the prediction of anxiolytic-like effects of compounds (Millan, M. J. et al., Neuropharmacology 2002, 42, 677-684).

Subjects:

The present studies were performed in accordance with the animal care and use policies of Addex Pharmaceuticals and the EEC directives on the protection of animals used for experimental and other scientific purposes (86/609/EEC and subsequent revisions). Male C57BL6/j mice (20-30 g), were group housed in a temperature and humidity controlled facility on a 12 hour light/dark cycle for at least 5 days before use. Mice had access to food and water ad libitum except during marble burying experiments.

Assessment of Marble Burying:

The effect of compounds on marble burying behaviour in mice was tested. On the day of the test, animals were marked on their tails and weighed in a separate preparation room, 1 hour before drug administration. Test compound or vehicle was administered p.o. 60 minutes prior to the test session. Marble burying behaviour was tested in a separate experimental room. For the test, mice were placed individually into clear plastic cages (16×22×14 cm) with 5 cm of sawdust and 10 marbles evenly spaced against the walls of the cage. The mice were left undisturbed in the cages for 30 minutes. After removal of the mice from the test cages, the number of marbles buried was counted. A marble was considered buried if it was ⅔ or more covered.

Compound Administration

Test compounds were dissolved in a solution of 1% CMC. Test compounds were administered 60 minutes before testing by oral gavage (p.o.) in a volume of 10 mL/kg. In each assay, a vehicle and reference positive control groups were tested.

Statistical Analyses:

Statistical analyses were performed using GraphPad PRISM version 4.01 statistical software (GraphPad, San Diego, Calif., USA). Data were analyzed using a non-parametric Kruskal-Wallis test followed by a Dunn's multiple comparisons test. The significance level was set at p<0.05 when compared to the vehicle group.

Effect of Compounds in the Marble Burying Test in Mice:

At the doses of about 3 to 30 mg/kg, selected compounds of the invention significantly attenuate the marble burying behavior in mice.

Example C Vogel Conflict Drinking Test, Model of Anxiety in Rats

Anxiety models in rodents are used as standard tests to demonstrate anxiolytic-like properties of novel compounds. The Vogel conflict drinking model involves the conflict between thirsts and receiving mild shocks for drinking water (punished drinking). Water-deprived rats are placed in a chamber and they receive mild electric shocks every time they drink. The shocks suppress drinking and anxiolytics reverse this shock-induced suppression of drinking. The Vogel conflict drinking model was first proposed as a screening model for anxiolytics (Vogel, J. R. et al., Psychopharmacologia 1971, 21:1-7) and is widely accepted as a robust model for testing the anxiolytic-like properties of compounds (Millan, M. J. and Brocco M., Eur. J. Pharm. 2003, 463:67-96).

Subjects:

The present studies were performed in accordance with the animal care and use policies of Addex Pharmaceuticals and the EEC directives on the protection of animals used for experimental and other scientific purposes (86/609/EEC and subsequent revisions). Male Sprague-Dawley rats (320-420 g) were housed in a temperature and humidity controlled facility on a 12 hours light/dark cycle for at least 5 days before use. Rats had access to food ad libitum except during Vogel conflict drinking model experiments. Rats had access to water ad libitum until 48 hours prior to the test session.

Assessment of Vogel Conflict Drinking:

The effect of compounds on drinking in the Vogel conflict drinking model in rats was tested. Test chambers are housed in sound-attenuating boxes and each chamber contains a stainless steel drinking spout and a steel grid floor (MedAssociates, Georgia, Vermont, USA). Forty-eight hours prior to the test session, rats were habituated to the test chambers for 10 minutes. Water was removed from the rats immediately after the habituation session. Twenty-four hours before the test session, rats were again placed into the test chambers and allowed to drink for 4 minutes. Rats were then allowed 1 hour of access to water and then water was removed. On the test day, rats were brought to the test room at least 30 minutes before the test session. Rats were placed individually into the test chamber for a 5 minute session. Rats received a shock every 20^(th) lick on the drinking spout. The number of punished drinks was counted automatically by the computer interface. The number of punished drinks was compared between treatment groups. An increase in the number of punished drinks in rats treated with a compound is interpreted as an anxiolytic-like effect.

Compound Administration:

Test compounds were suspended in 1% CMC. Test compounds were administered by oral gavage (p.o.) in a volume of 3 ml/kg 1 or 2 hours before testing. In each assay, a vehicle and reference positive control groups were tested.

Statistical Analyses:

Statistical analyses were performed using GraphPad PRISM version 4.01 statistical software (GraphPad, San Diego, Calif., USA). Data were analyzed using one-way analysis of variance (ANOVA) followed by Bonferroni's multiple comparisons. The significance level was set at p<0.05 when compared to the vehicle group.

Effect of Compounds on the Vogel Conflict Test in Rats:

At the doses of about 0.3 to 3 mg/kg, selected compounds of the invention increase the number of punished licks in the Vogel conflict test in rats.

Example D Elevated Plus Maze Test, Model of Anxiety in Mice or Rats

Anxiety models in rodents are used as standard tests to demonstrate anxiolytic-like properties of novel compounds. The elevated plus maze is an animal model of anxiety, which has been validated behaviourally, physiologically, and pharmacologically (Pellow et al., J. Neurosci. Methods 1985, 14: 149-167). Following placement on the maze, untreated animals (mice or rats) tend to avoid the open arms and spend most of their time in the closed arms. Anxiolytic drugs such as benzodiazepines increase open arm exploration. Anxiety in the elevated plus maze is measured by examining the time spent on the open arms as well as open arm entries. In addition, closed arm entries are measured and used as a general activity score.

Subjects:

The present studies were performed in accordance with the animal care and use policies of Addex Pharmaceuticals and the EEC directives on the protection of animals used for experimental and other scientific purposes (86/609/EEC and subsequent revisions). Male Sprague-Dawley rats (200-300 g) or male C57/Bl6J mice (20-30 g) were housed in a temperature and humidity controlled facility on a 12 hours light/dark cycle for at least 5 days before use Animals had access to food ad libitum excepted during elevated plus maze experiments.

Assessment of the Elevated Plus-Maze Test:

The elevated plus-maze consists of four plastic arms connected by a central square, the arms are all horizontal and at 90° angle from each other making the shape of a plus sign. The maze is raised to a height of 50 cm from the ground. Two of the opposite arms have high plastic walls whereas the other two opposite arms do not. These arms are therefore referred to as the enclosed and open arms, respectively. The central square is not enclosed and the animal is initially placed in this area facing an enclosed arm.

The animals had free access to all 4 arms for a 5 minute period. During this time, the number of entries into, and the time spent on each type of arm were recorded. The results were presented as:

Percentage of total number of entries onto open arms.

Percentage of time spent on the open arms.

Total number of entries into all arms.

On the day of the test, animals were marked on their tails and weighed in a separate preparation room before drug administration. Test compound or vehicle was administered p.o. 60 minutes prior to the test session.

Compound Administration:

Test compounds were dissolved in a solution of 1% CMC. Test compounds were administered 60 minutes before testing by oral gavage (p.o.) in a volume of 10 mL/kg. In each assay, a vehicle and reference positive control groups were tested.

Statistical Analyses:

Statistical analyses were performed using GraphPad PRISM version 4.01 statistical software (GraphPad, San Diego, Calif., USA). Data were analyzed using one-way analysis of variance (ANOVA) followed by Bonferroni's multiple comparisons test. The significance level was set at p<0.05 when compared to the vehicle group.

Effect of Compounds in the Elevated Plus Maze Test:

At the doses of about 0.3 to 3 mg/kg, selected compounds of the invention increase both the number of entries and the time spent on the open arms.

Thus, the positive allosteric modulators provided in the present invention are expected to increase the effectiveness of GABA or mGABA_(B) agonists at GABA_(B) receptor. Therefore, these positive allosteric modulators are expected to be useful for treating, or preventing, ameliorating, controlling or reducing the risk of various central nervous system disorders as well as other disorders associated with GABA_(B) dysfunction in a mammal, including a human, the treatment or prevention of which is affected or facilitated by the neuromodulatory effect of GABA_(B) positive allosteric modulators In particular, the neurological and psychiatric disorders associated with GABA_(B) receptor dysfunction, include one or more of the following conditions or diseases: anxiety, depression, epilepsy, schizophrenia, cognitive disorders, spasticity and skeletal muscle rigidity, spinal cord injury, multiple sclerosis, neuropathic pain and craving associated with cocaine and nicotine, amyotrophic lateral sclerosis, cerebral palsy, posttraumatic stress disorders or gastro-intestinal disorders, cerebral palsy, psychosis, panic disorder At present, the fourth edition of the Diagnostic & Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association provides a diagnostic tool for the identification of the disorders described herein. The person skilled in the art will recognize that alternative nomenclatures, nosologies, and classification systems for neurological and psychiatric disorders described herein exist, and that these evolve with medical and scientific progress. Where the invention is said to relate to the use of a compound or composition according to the invention for the manufacture of a medicament for e.g. the treatment of a mammal, it is understood that such use is to be interpreted in certain jurisdictions as a method of e.g. treatment of a mammal, comprising administering to a mammal in need of such a treatment, an effective amount of a compound or composition according to the invention. Because such positive allosteric modulators of GABA_(B) receptors, including compounds of Formula I, enhance the response of GABA_(B) receptors to GABA, it is an advantage that the present methods utilize endogenous GABA. Because positive allosteric modulators of GABA_(B) receptors, including compounds of Formula I, enhance the response of GABA_(B) receptors to agonists, it is understood that the present invention extends to the treatment of neurological and psychiatric disorders associated with GABA dysfunction by administering an effective amount of a positive allosteric modulator of GABA_(B) receptors, including compounds of Formula I, in combination with a GABA_(B) agonist. The compounds of the present invention may be utilized in combination with one or more other drugs in the treatment, prevention, control, amelioration, or reduction of risk of diseases or conditions for which compounds of Formula (I) or the other drugs may have utility, where the combination of the drugs together are safer or more effective than either drug alone.
